Dr. Davis started her career in dentistry in 1988 as a dental hygienist. After receiving a certificate in dental hygiene from the University of Pittsburgh, she worked as a dental hygienist while pursuing a bachelor of chemistry degree at Lebanon Valley College, where she received numerous awards in organic chemistry and served as a research assistant under the guidance of Dr. Carl T. Wigal, PhD. Dr. Davis has also published in The Journal of Organic Chemistry.


Subsequent to a 10-year career as a dental hygienist, Dr. Davis entered dental school at the University of Pennsylvania. Again, doing research was an important part of her educational process; she received a grant from the National Institutes of Health for work in the area of bone formation. Upon graduation from the University of Pennsylvania, Dr. Davis joined the practice of Dr. Frederick S. Johnson. Together, they practice a philosophy of comprehensive and esthetic dentistry. In 2007, Dr. Davis bought this practice. In time, the practice became known as Cleona Dental, LLC.


Dr. Davis is a member of the American Dental Association (ADA), Pennsylvania Dental Association (PDA), the American Academy of Cosmetic Dentistry (AACD), the American Academy of Dental Sleep Medicine (AADSM), and an Alumni and Visiting Faculty of The Pankey Institute for Advanced Dental Education. She has served on the ADA Committee of the New Dentist and the PDA New Dentist committee. She is the past president of the Fourth District Dental Society.
